Dear Fred--I know you meant well, but I, and many friends, feel this was a poor decision. Surely you could make this an option by the table host to hide or reveal declarer to the dummy. I can admit or bar kibbitzers as well as any chat with them. As table host, I also have the option to boot an obnoxious player. I also have the option to leave a table when dummy is rude to me when I am not the host. Why have you chosen the nuclear option when there are less drastic methods? I teach large classes of beginners (100+/class) twice a year. I then send them onto BBO for practice. Many eventually get addicted to the one hour tournament games. I often play a few hands with them to get them up to speed and to help overcome their reluctance to play with strangers. If I cannot see dummy when they declare, it significantly lessens any ability I have to help them. Please reconsider. I also miss the bell ringing when it is my turn to bid or play. Please reconsider or make this an option. Thanks
